OK i solved my issue by starting
apparmor. Something has disabled it i guess during a major update which includes kernel update apparmor gets inactive and after reboot snap confine problem appears. to check i f appamor is running do the following
$ systemctl status apparmor
● apparmor.service - AppArmor initialization
Loaded: loaded (/lib/systemd/system/apparmor.service; disabled; vendor preset: disabled)
Active: inactive (dead)
If the output says its inactive enable it by
systemctl start apparmor and then run your snap.
